oooh...hard question! I can't really pick a favorite, either...If I could, then Amazon would not be getting so much of my money every time I think I need a new book! :P I must say I do find myself referring to All About Quilting from A to Z, as the name implies it has some great tips about a little bit of everything. Since I am fairly new to fmq, the other book I really love is Show Me How to Machine Quilt...I have several books on the subject, but this one just really "clicks" with me!
